go get github.com/TuanKiri/socks5

Create your .go file. For example: main.go.

package main

import (
	"context"
	"log"
	"os/signal"
	"syscall"

	"github.com/TuanKiri/socks5"
)

func main() {
	ctx, stop := signal.NotifyContext(context.Background(), syscall.SIGINT, syscall.SIGTERM)
	defer stop()

	srv := socks5.New()

	go func() {
		if err := srv.ListenAndServe(); err != nil {
			log.Fatal(err)
		}
	}()

	<-ctx.Done()

	if err := srv.Shutdown(); err != nil {
		log.Fatal(err)
	}
}

Run your server:

go run main.go

The following curl example shows how to use the proxy server:

curl -x socks5:https://127.0.0.1:1080 https://example.com

See the tests and examples for more information about package.

• Why can't connect to socks proxy server?

  Not all applications and browsers support socks authentication or socks protocol. You may need extension for Chrome or another browser.

If you have any questions, you can ask in GitHub Discussions.

• The proof of work for the UDP association was done using qBittorrent - a BitTorrent client.
